Kona-low floods Oahu as Wahiawa Dam danger triggers North Shore evacuations

Oahu remains under a flash flood warning with a flash flood emergency on the North Shore as a Kona-low storm system dumps heavy rain statewide. Authorities say Wahiawa Dam is at imminent risk of failure, prompting evacuations downstream in Waialua and Haleiwa and the opening of multiple shelters. The Hawaii National Guard, Coast Guard, and Army personnel are assisting with rescues and evacuations, and power outages have affected thousands in evacuation zones. Forecasters warn more heavy rain is possible, and a statewide flood watch and additional advisories extend through the weekend, with Maui also under flood advisories and Hawaii Island facing a winter-storm watch for the peaks.
